The issue of this dissertation is the relationship between Vocational Education and Training (VET) in general and VET for building and construction in particular, as well as implications of the fact that Swedish VET is carried out both in school and in working life. Vocational construction education includes a three year Construction Programme at upper secondary school followed by two to three years of on-the-job training in the construction industry. In this case study of an upper secondary Construction Programme, the school based daily instruction as well as work based training, is explored and documented. These constitute a base for descriptions and analysis of education as a whole from the perspective of Cultural Historical Activity Theory (CHAT). The aim of the analysis is to identify the main motives for vocational construction education. The case study results are further based on descriptions and CHAT-analyses of the historical development of construction work as well as of Swedish VET in general and of vocational construction area in particular. The case study illustrates that two activities form vocational construction education; the dominating activity being construction production, and school-activity. The terms of construction industry seem to greatly determine the realisation of the school based construction production activity.  E.g. teamwork is emphasised in both activities. The school activity is marked by the implementation of infusion of core subjects by vocational subjects, aimed at preparing the students for continued professional development in the trade. The conclusion drawn here is that the new Swedish apprenticeship seems to contribute to a narrow professional knowledge base, whereas the use of infused core subjects seems to contribute to a broader professional knowledge base.
